apply_quat(3alleg4)              Allegro manual              apply_quat(3alleg4)



NAME
       apply_quat - Multiplies a point by a quaternion. Allegro game programming
       library.

SYNOPSIS
       #include <allegro.h>


       void apply_quat(const QUAT *q, float x, y, z, *xout, *yout, *zout);

DESCRIPTION
       Multiplies the point (x, y, z) by the quaternion q, storing the result in
       (*xout, *yout, *zout). This is quite a bit slower than apply_matrix_f(),
       so only use it to translate a few points. If you have many points, it is
       much more efficient to call quat_to_matrix() and then use
       apply_matrix_f().
